In the past, porcelain-fused-to-metal crowns were a popular solution for damaged or decayed teeth. While they were certainly effective, patients may notice a black line forming near the gums out of nowhere. Unfortunately, these dark lines are unsightly and can ruin a natural-looking appearance. If you find yourself experiencing this issue, you may have several lingering questions in mind. Continue reading to learn what causes a black line around a dental crown and what your dentist can do to help!

What Causes a Black Line Around a Dental Crown?

A black line forming around a dental crown can be caused by two things. That includes:

Metal From the Dental Crown Showing

The most common reason for a black line forming near the gums is because underneath older-style crowns is a layer of metal, usually gold alloy. It provides strength as porcelain tends to be weak under force. When your crown was fitted, you may not have noticed a black line because it was hidden underneath the gum line. However, the border between your crown and natural look may become exposed as your gums recede due to aging. As a result, the black line from the metal is visible.

Shadows Around the Crown

In rare cases, the black line may simply be an optical illusion. An ill-fitting dental crown can cast a shadow over the surrounding area, creating the appearance of a black line. Of course, it’s important to note that these black lines are much less prominent than those caused by the metal showing from the crown.  

How Your Dentist Can Help

More often than not, the only viable solution for a black line around a dental crown is to replace the restoration with a new one. These days, most dental practices offer metal-free dental crowns. Modern restorations are usually made entirely of ceramic, which means you never have to worry about a black line forming! Since the material can be color-matched to your enamel, your crown will blend seamlessly with your remaining teeth, allowing you to enjoy a natural-looking smile. Even without metal, these new crowns are strong enough to withstand the chewing of virtually any food. Best of all, they can last up to 15-20 years with proper maintenance.
